 /**
  * Site content provider.
  * A site content provider is an abstraction of each site internal
  * organization. It allows the site content to be accessed in
  * a standard way regardless of the internal organization. All concrete site
  * implementations need to implement a site content provider.
  * <p>
  * Clients may implement this interface. However, in most cases clients should
  * directly instantiate or subclass the provided implementation of this
  * interface.
  * </p>
  * <p>
  * <b>Note:</b> This class/interface is part of an interim API that is still under development and expected to
  * change significantly before reaching stability. It is being made available at this early stage to solicit feedback
  * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
  * (repeatedly) as the API evolves.
  * </p>
